JOURNAL-BOX.

SPECIFICATION forming part of Letters Patent No. 366,9-81, dated July19, 1887.

Serial No. 211,835. (No model.)

To all whom t may concern'.

Be it known that LWTLLLTM W. SMELLEY, a citizen of the United States,and a resident of Bound Brook, Somerset county, New Jersey, haveinvented certain new and useful Improvements in Journal-Bearings, ofwhich the following is a specification.

My invention relates to journals and journal-boxes, and moreparticularly to that class oi' journals and journal-boxes which are provided with pockets or recesses tilled with some anti-frictioncomposition; and it has for its object to improve the constructionofsueh articles so that they are better adapted to receive and retainthe composition in place, whether used as full cylinderbearings ordivided cylinder-bearings.

To these ends my invention consists in sub dividing the pockets orrecesses by transverse stops and in making a cylinder-bearing with twoor more continuous longitudinal strips or bars extending throughout thesame, which are not cnt or recessed, so that the cylinderbearing may bedivided longitudinally, as hereinafter stated.

Referring` to the accompanying drawings for amore thorough descriptionof my invention, Figure 1 is a plan view of one form of bearing, showingmy improvement. Figs. 2 and 3 are respectively side and perspectiveviews of the core. Fig. 4 is a sectional View of the core and box. Fig.5 is a section through the bearing, showing the inclined sides of thepockets. Fig. 6 is a section through the bearing, taken on aline atright angles to the line on which Fig. l is taken. Fig. 7 is a side viewshowing my invention applied to a journal.

Thejournal or bearing may be of any of the usual forms, and I haveselected one convenient form to illustrate my improvements; and thefirst peculiarity consists in the arrangement of the receptacles orpockets within which is contained the anti-friction substance whichserves as a lubricant to prevent friction and wear.

Heretofore pockets have been made in the form of screwtlireads or radialopenings or recesses; but ithas been found very diiiicult,if notimpossible, to practically make such. pockets,

owing to the diiiiculty of withdrawing the core from the mold withoutdestroying the latter, and such recesses have had to be cut by millingor drilling,which is expensive and impractieable. In Patent No. 209,0Sithere is described and shown a practical way of ranged at right anglesto the sides or trend of the grooves, and arranging the stops in eachaiternategroove in a line, the lubricating material may be moreeffectually applied to and retained in the pockets, and consequently producing a better and more lasting bearing.

InFig. LA is the metal of thebearing,hav ing the grooves B, which areinclined relatively to the longitudinal axis ol' the bearing and are`filled with the lubricating material, the stops O O being arranged tosubdivide the grooves into pockets, and are arranged at right angles tothe sides of the grooves, as shown,while the stops in eachalternategroovc are in a line. The general form and arrangement of thesepockets will be best understood by referring to Figs. 2 and 3, whichillustrate the form of core used in forming a bearing such as is shownin Fig. l. The cylindrical body of the core D has projections E, whichcorrespond, essentially, to parts of a series of parallel disks throughwhich the body D of the core may be considered as extending, the centersof Ithe disks coinciding with the axis of the body, and each disk beingat an angle to the said aXis,as shown. The recesses F to form the stopsare arranged at right angles to the projections E. Vhen the bearing iscastfrom such a core, it will have a central longitudinal cylindricalopening or bore and a series of pockets parallel to each other, but eachat an angle to the axis. By this arrangement a core can be iliade in theordinary two-part core-box, as shown in Fig. 4, which core will drawreadily without liability of breaking. Thus the two parts G G ofthecore-box can be separated from the core, inasmuch as the sides ot' theprojections E coincide with vertical planes at right angles to the planeet the boxes. It will be observed f esegui that in order to accomplishthis result ,care must be exercised in placing the core in the boxproperly. Forinstance, if the sections of the box were formed tocoincide to that portion of the core upon one side o f the line y, Fig.3, the core would not draw from the box; but by making each portion'ofthe box coincide with one ofthe parts of the core divided on the line wthe core can readily be drawn, andby so using the core I am enabled tocast in one piece a complete bearing having the grooves or pockets forthe composition, as shown, thus avoiding all cutting and drilling. Itwill be observed that the sides of each pocket in the bearing areinclined to the bore, as shown more clearly in Fig. 5, therebyprovidinga sort of undercut pocket well adapted for the retention of thelubricating material.

By the use of thestops in the channels Iam enabled to more compactly llthe pockets, as the material may be thoroughly pressed therein bymandrels, the twisting and screwing of which iu forcing the materialsolidly in place is liable to dislodge some portions thereof without thestops which eifectually prevent it. Moreover, in actual use of thebearing, if any foreign substance gets lodged in the box or thelubricant adheres to the revolving surface, the stops check it-,Whilethe stops act as braces to the sides of the pockets, and I can thereforemake the metal surfaces narrower and increase the width of thelubricant-surface, and the case of the bearing may be made thinner,decreasing its Weight Without decreasing its strength.

It is often desirable to make half or sectional bearings, audit has beenfound expedient to cast a full cylinder and cut it into the desiredsections; but the cutting was liable to disturb the graphite lubricantin the pockets, and in order to lavoid this difficulty I cast thecylinder with continuous longitudinal strips of metal, H, and thendivide the cylinder by any suitable instruments or tools upon or throughthis strip, thereby leaving the sections with closed ends, as shown in,Fig. l. In order to do this, it is only necessary to cut one or moregrooves,as may be desired, in the core, as shown at I, Fig. 4., and theresult will be the continuous bars or ribs H when the casting is made,and the cylinder may then .be cut without disturbing the graphitecomposition, and each section will have a sound and wellfinished edge.Furthermore, the faces may be cut or filed to adjust the bearing withoutdisturbing the graphite. J

Iam aware thatjournal-bearings have been formed with separate cavitiesadapted to receive lubricating material. I 'am also aware thatjournal-boxes have been provided with metallic bearing-strips arrangedon straight lines longitudinally to the axis thereof, there being formedin each such 'strip 'a series of recesses or slots adapted to receivelubricating material; but Ibelieve that I am the rst to have invented aconstruction wherein the grooves for the lubricating material passaround the longitudinal axis of the bearing, either spip rally ordirectly, and to have divided such grooves into 'pockets in the mannerset forth.

The advantages incidenty to arranging the grooves spirally around thejournal-bearing are, among other things, that every part of the shaftrevolving therein is brought into intimate contact with the lubricatingmaterial at every revolution.

The bearing which I have described is inte gral, which term I use todistinguish my iuf vtional bearing, itwill be understood that it may beequally well applied to journals and bearings of all shapes and sorts,and while I have shown the stops as arranged in alternate rows in thegrooves it will be understood that this is not an essential feature ofmy invention, but that theyV may be arranged in many ways to formpockets of various sizes withou departing from my invention.

Vhat I claim is 1. An integral journal or bearing having vgroovestherein extending around the longitudinal axis thereof, said groovesbeing divided into pockets for the reception and re tention of thelubricant, substantially as described.

2. An integral bearing having internal parallel recesses with undercutsides extending around the longitudinal axis thereof, said recessesbeing, divided into pockets for the reception and retention of thelubricating material, substantially as described.

8. An integralbearing having recesses or pockets therein for thereception of the lubricant and having the continuouslongitudinal stripsor bars H, through which the bearing may be'divided, substantially asdescribed.

4.. A cast journal-bearing having inclined recesses passing around itslongitudinal axis, said recesses being divided into pockets by stopsarranged at right angles to the sides of the grooves, substantially asdescribed.

5. A journal-bearing having inclined recesses passing around itslongitudinal axis, said ,recesses being divided into pockets by stops GG, the stops in the alternate grooves being in line with each other,substantially as described. y i
